Methodology: (I deliberately set out to see what I could do limiting myself to blending modes).

Create a mask for sky and foreground using color range.
Sky = blend mode 'soft light' at 60%
Foreground = blend mode 'color dodge' 25%
slight contrast with curves for foreground
I actually made the foreground a bit cooler - it looked too much like a paste-in otherwise (and admittedly still does to some extent).
USM 10, 10, 0 (variation on local contrast enhancement) for foreground.
